![]() ![]() Qualitative findings suggest that there was declining support for the initiative over time, meaning that potential benefits may not have been achieved. However, the mechanisms of these benefits are unclear as there was insufficient data from physical activity to draw robust conclusions. The implementation of a dance mat exergaming scheme was associated with improvement in anthropometric measurements and parameters of health-related quality of life. There was also evidence of improvement in some health-related quality of life parameters: psychological well-being (2.5, 95% CI: 0.1 to 4.8) and autonomy and parent relation (4.2, 95% CI: 1.4 to 7.0). ![]() However, compliance with accelerometers at follow-up was poor. ![]() There was a negative intervention effect on total physical activity (-65.4 cpm CI: -12.6 to -4.7), and light and sedentary physical activity when represented as a percentage of wear time (Light: -2.3% CI: -4.5 to 0.2 Sedentary: 3.3% CI: 0.7 to 5.9). Data on physical activity (accelerometer), anthropometrics (weight, BMI and percentage of body fat), aerobic fitness (20-m multistage shuttle run test), health-related quality of life (Kidscreen questionnaire), self-efficacy (children’s physical activity self-efficacy survey), school attendance, focus groups with children and interviews with teachers were collected at baseline and approximately 12 months follow-up. Participants were recruited from five schools in intervention districts (n = 280) and two schools in neighbouring control districts (n = 217). The aim of this natural experiment was to examine the effect of introducing the dance mat exergaming systems on physical activity and health-related outcomes in 11–13 year old students using a non-randomised controlled design and mixed methods. In January 2011, dance mat systems were introduced in secondary schools in two districts in England with the aim of promoting an innovative opportunity for physical activity. However, large effectiveness studies are rare. Exergaming has been proposed as an innovative method for physical activity promotion. ![]()
